Constructor & Destructor Documentation

Gecode::Region::Region ( void   )  [inline]

Initialize region.

Definition at line 352 of file region.hpp.

Gecode::Region::~Region ( void   )  [inline]

Return memory.

Definition at line 373 of file region.hpp.


Member Function Documentation

void Gecode::Region::free ( void   )  [inline]

Free allocate memory.

Note that in fact not all memory is freed, memory that has been allocated for large allocation requests will not be freed.

Definition at line 356 of file region.hpp.

template<class T >
T * Gecode::Region::alloc ( long unsigned int  n  )  [inline]

Allocate block of n objects of type T from region.

Note that this function implements C++ semantics: the default constructor of T is run for all n objects.

Definition at line 386 of file region.hpp.

template<class T >
T * Gecode::Region::alloc ( long int  n  )  [inline]

Allocate block of n objects of type T from region.

Note that this function implements C++ semantics: the default constructor of T is run for all n objects.

Definition at line 394 of file region.hpp.

template<class T >
T * Gecode::Region::alloc ( unsigned int  n  )  [inline]

Allocate block of n objects of type T from region.

Note that this function implements C++ semantics: the default constructor of T is run for all n objects.

Definition at line 400 of file region.hpp.

template<class T >
T * Gecode::Region::alloc ( int  n  )  [inline]

Allocate block of n objects of type T from region.

Note that this function implements C++ semantics: the default constructor of T is run for all n objects.

Definition at line 405 of file region.hpp.

template<class T >
void Gecode::Region::free ( T *  b,
long unsigned int  n 
) [inline]

Delete n objects allocated from the region starting at b.

Note that this function implements C++ semantics: the destructor of T is run for all n objects.

Note that the memory is not freed, the only effect is running the destructors.

Definition at line 412 of file region.hpp.

template<class T >
void Gecode::Region::free ( T *  b,
long int  n 
) [inline]

Delete n objects allocated from the region starting at b.

Note that this function implements C++ semantics: the destructor of T is run for all n objects.

Note that the memory is not freed, the only effect is running the destructors.

Definition at line 419 of file region.hpp.

template<class T >
void Gecode::Region::free ( T *  b,
unsigned int  n 
) [inline]

Delete n objects allocated from the region starting at b.

Note that this function implements C++ semantics: the destructor of T is run for all n objects.

Note that the memory is not freed, the only effect is running the destructors.

Definition at line 425 of file region.hpp.

template<class T >
void Gecode::Region::free ( T *  b,
int  n 
) [inline]

Delete n objects allocated from the region starting at b.

Note that the memory is not freed, the only effect is running the destructors.

Definition at line 430 of file region.hpp.

template<class T >
T * Gecode::Region::realloc ( T *  b,
long unsigned int  n,
long unsigned int  m 
) [inline]

Reallocate block of n objects starting at b to m objects of type T from the region.

Note that this function implements C++ semantics: the copy constructor of T is run for all $\min(n,m)$ objects, the default constructor of T is run for all remaining $\max(n,m)-\min(n,m)$ objects, and the destrucor of T is run for all n objects in b.

Returns the address of the new block.

Definition at line 437 of file region.hpp.

template<class T >
T * Gecode::Region::realloc ( T *  b,
long int  n,
long int  m

int  n,
int  m

Returns the address of the new block.

Definition at line 466 of file region.hpp.

void * Gecode::Region::ralloc ( size_t  s  )  [inline]

Allocate memory from region.

Definition at line 361 of file region.hpp.

void Gecode::Region::rfree ( void *  p,
size_t  s 
) [inline]

Free memory previously allocated.
